Yan Zhao 46d14e1709 drm/i915/gvt: Fix bug in getting msg length in AUX CH registers handler
Msg length should be obtained from value written to AUX_CH_CTL register
rather than from enum type of the register.

Commit 0cad796a22  ("drm/i915: Use REG_BIT() & co. for AUX CH registers")
incorrectly calculates the msg_length from reg type and yields below
warning in intel_gvt_i2c_handle_aux_ch_write():
"i915 0000:00:02.0: drm_WARN_ON(msg_length != 4)".

Fixes: 0cad796a22 ("drm/i915: Use REG_BIT() & co. for AUX CH registers")
